>>1216752I took the tension mechanism on my titanium b17 apart and the reason the bolt is so short is because it snapped. It is supposed to be 60 mm long but is only 20 mm. It looks like it likely happened during manufacturing, limey bastards. I can see teeth marks in the tension shackle from when the bolt had been longer, and the angle indicates it would have been pressing hard against the anchor. Fully inserting the bolt with a power tool caused it to shear at the end of the tension bolt.
